Abstract
The utility model relates to a seed metering device driving device in agricultural machinery. When the seeder is used in field, the rotation of the land wheel of the seeder is unstable due to various reasons, and the slippage is large, so that the seeds are missed. The utility model provides a seed metering ware drive arrangement based on tractor front wheel rotational speed, the device mainly comprises speed sensor and drive arrangement two parts. A sensor is arranged near a front wheel axle of the tractor, the sensor is used for measuring the rotating speed of the front wheel, the pulse output end of the sensor is connected with the input end of a stepping motor and used for driving the stepping motor to rotate, and the stepping motor drives the seed sowing device to rotate so as to achieve the purpose of uniform seed sowing. The spacing of the seeds can be adjusted by adjusting the subdivision number of the stepping motor, so that the spacing which is most suitable for the growth of the seeds is achieved, and the method is suitable for the growth conditions of different crops. Thereby achieving the purpose of increasing the yield.
Description
Technical field:
The utility model relates to a kind of seeding unit drive unit in the agricultural machinery.
Background technology:
Seeding unit commonly used on the sower is divided into mechanical type seeding unit and pneumatic type seeding unit, the seeding of pneumatic type seeding unit accurately but complex structure for the bigger crop seed of sowing size variation, be advisable as use pneumatic type sowers such as corns.The mechanical type seeding unit is simple in structure but Seeding Uniformity is relatively poor, for crop seed such as pill beet, and the normal mechanical type seeding unit that adopts such as wheat, with regard to China's present circumstances, the mechanical type seeding unit still occupies larger proportion.The existing drive unit major part that is used for the mechanical type seeding unit on the sower is to drive the seeding unit seeding by the ground wheel drive of sower, the mode of chain gear transmission at present, but because when farm work, the face of land that the land wheel of sower is mostly walked on the soft face of land or had stalk to cover, the unequal reason in the face of land tends to cause that land wheel rotates steadily, slippage is big in addition, thereby causes the broadcast leakage phenomenon of seed.The rate of skidding of sower land wheel sometimes can be up to 20% during farm work.Seeding uniformity is caused very big influence.Eliminate the slippage of driving wheel, can make seeding more even, reduce leakage sowing rate, increase grain yield.And most existing mechanical type seeding unit, for the gearratio of different crops owing to seeding quantity different needs replacing seeding unit, thereby with a lot of inconvenience.
Summary of the invention:
When overcoming existing sower ground wheel drive because big slippage causes the defective that the seed leakage sowing rate is big and adjustment is inconvenient, the utility model provides a kind of seeding unit drive unit based on the tractor front wheel rotation speed, because the tractor front-wheel has the less rate of skidding than trailing wheel and sower land wheel, sensor is installed in the tractor front-wheel, utilize sensor to measure the speed of travel of tractor, sensor output control step motor rotates, and controls seeding speed according to the speed of travel.Therefore this device can improve seeding uniformity, can also regulate the seed spacing according to the needs of Different Crop.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a schematic diagram of the present utility model.
1. sensors, 2. tractor front-wheels, 3. supports, 4. ploughs, 5. stepper motors, 6. seeding units among the figure
Embodiment:
In the farm work unit, the tractor front-wheel has the less rate of skidding with respect to tractor trailing wheel and sower land wheel.In order to realize kind of the purpose that reaches volume increase that evenly falls, the utility model provides a kind of seeding unit drive unit based on the tractor front wheel rotation speed.This device mainly is made up of speed measuring device and drive unit two parts.Near sensor installation (1) tractor front-wheel (2) axletree, utilize sensor that front wheel rotation speed is measured, the pulse output end of sensor connects the input of stepper motor (5), be used for driving the rotation of stepper motor, the rotation of stepper motor drive seeding unit (6) reaches the purpose of even seeding.Can also adjust the spacing of seed by the segmentation number of regulating stepper motor, reach the spacing of suitable seed growth, be used for adapting to the growth conditions of Different Crop.Thereby reach the purpose of volume increase.So design meets agronomy volume increase requirement based on the seeding unit drive unit of tractor front wheel rotation speed.
Become according to the unit speed of travel based on the sower of this device sowing speed when the farm work, can reach even sowing, improved seeding quality greatly, reduce leakage sowing rate, improve seeding uniformity, reach the volume increase purpose.
Claims (1)
- (1) a kind of seeding drive unit based on the tractor front wheel rotation speed, this device mainly is made up of speed measuring device and drive unit two parts, it is characterized in that: near sensor installation tractor front-wheel axletree, the pulse output end of sensor connects the input of stepper motor, and stepper motor drives the seeding unit seeding.
